This small voltage regulator was found in a 1969 EEE. More powerful transistors can be used to obtain a higher output current.
The components used in this 80's circuit are not common today. The circuit is very sensitive and must...
This circuit was obtained in the publication 101 Electronics Projects of 1979. The circuit can be...
Originally designed for WWV (Standard Time Station) signals, it lets 1 kHz tones pass by rejecting...
